The formation of an apple and pollen tubes

ONTOLOGICAL QUESTIONS- 27
"These are the Alps.
The world's longest tunnel was built here.
57 kilometres.
What was used to correctly move forward in the darkness of the mountain while digging the tunnel?
Magnetic field measurements were made.
GPS-like geodetic devices were used.
Laser scanners and radar systems were used.
Measurements were constantly checked with accelerometers and gyroscopes.
And a giant drill bit with a diameter of 9 meters was used to create the tunnel.
Only by using all of these method was it possible to reach exactly the right point.
A great success.
Construction lasted 17 years.
The tunnel opened in 2016.
There is a similar process on a microscale in all plants.
Let's understand the how small this is.
Let's consider this cucumber as the stem of the apple flower.
Let this be the stigma.
Let this pin be a sperm cell.
And this one is the tunnelling cell.
The tunnelling cell will create a pollen tube.
It will extend like this.
The sperm cell will advance through the opened tunnel.
The travelling of pollen tubes along the plant stem is a seemingly simple but inconceivable phenomenon."
